Find the area of the triangle 9yd 3yd 8 yd

Step-by-step explanation:

You can use Heron's formula for this question.

Heron's Formula: Area of Triangle = root s (s-a) (s-b) (s-c)

Where s = perimeter/2 and a, b, and c are the side lengths.

So solving ...

s = perimeter/2

= (9yd + 3yd + 8yd) / 2

= 20yd/2

= 10yd

A = root 10yd (10yd-9yd) (10yd-3yd) (10yd-8yd)

= root 10yd (1yd) (7yd) (2yd)

= root 140yd

= 2 root 35
